Application inea october 15, 1923. vsenai- No. 668,726.

To alllwhom t may concern: 1

Be it known that I, "EDGAR D. MIsNniz, a citizen of the United States of'America, residing at Detroit, in the countyl of l/Vayne and State of Michigan, have invented cerA tainnew and useful Improvements in Shock` Absorbers, of which the followingis aspec#` iication, reference being had therein tothe accompanying drawings.

The'invention relates to shockabsorbersy and is particularly applicable to motor Vve-V hicles. One of the objects of the invention is the provision of a shock absorber which is f movement of the .axle toward tli-e frame of f themotor vehicle.

Vith these as well as other objects in view, the invention resides inthe novel features of constructionl and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings;

Figure 1 is an end view of a shock absorbl er embodying my invention;

Figure 2 is acsectional elevation thereof; Figure 3 is an end view of a modified construction of my shock absorber;

Figure t is a section thereof; j Figures 5 and 6 are-respectively side and edge views of the clip for securingv the strap to the spring. l

,1 is the frame of the shockabsorber'c'om# prising the pair of complementarysections 2 and 3 secured to each other by the'bolts 4.

This vframe is secured to the'undeiside-of the frame of the motor vehicle and in the present instance is designed to be secured to the underside of the frame of almakeof motor vehicle having the channel side sills 5 and the V-shaped` cross bar 6- of angle section secured to the webs of the -side sills. The shock absorber lframes have the lateral lugs'? through-which the bolts 8 extendffor' securing Vthe shock absorber frame to the motorv vehicle frame. Y f

Each of the sections 2 and 3 isprovided with the internal channel`9 which is adapted to register withk the ,internal channel up on the other section to form armain channel sl-idably engaged in by the strapv or web 10.

This main channel isapproximatelysemif at thelower front vportion where the strap or webv normally-engages the outer wall. One end ofthe 'strapor vweb lO is secured 6 0 circular and' y is so shaped that the strap or f web normally engagesy its inner-wall except.

by means of the clip 11 and the clamp 12, f tothe lower'flanges ofthe front axle 13,

while lthe opposite end is secured to the outer endjof thecoil spring 141, whichla't-`V ter is housed within the frame 1. `rrAs shown,

the complementary -sections 2 and 3 lof l thisframe have elongatedrecesses 15 which are adapted to register with each other and'coml municate with These recesses, when together, form a cylin-y drical `space for* receiving'the coil spring.

-By reason of the factthat in the above-inen-v tion typeyof motor vehicle, the dust pan 16 the internal channels 9."`

provides ybut veryl little clearance-for the pring extends substantialy vertically Vand beside/the front axle. v

s'hockabsorber, the frame housing for `the' Forthepurpose vof-limiting the relative movement ofthe axle and motorvehicle frame toward each other, I have provided thebumper 17 formed of suitable'yieldable material such asrubber. rlhis bumper is secured upon the framejjl, and as shown vis embraced lby the complementary 'sections 2 and 3 of the frame and so positioned that it is adaptedl to engage the Aupper face of the Y axle. n N Y For thepurpose o f Vlubricating the major portion of thefriction bearing surfacev'up'on the shock absorber fram'efor'the strap `or web, VI have formed the complementary sec- Y*tions 2. and 3 with the cross web 18, the cross web of` one of the sections having the lubril 1 l cant passage 19 opening into the groove 2Ol inthe lowerjwallfof the internalcliannel 9 that as the /strap or web 10 vslides withinthe channels 9, it'coines intocontact with 'i lubricant and thereby distributes the same loverthemajor portion of the friction :bearingsurface.v

Tol provide a fsimple and inexpensive means for securing the strap or web'to the springfwhich permits of easyassembly A`of the two, I provide thelike clipfmeinbers 21 securedY by suitable means to thestrap or web fandfeach providcdwitli a hooked or .benty i offeach section, the arrangementbeing'such y end 22, AV member is secured to each of the opposite sides ot the strap or Web and as a consequence, the hooked orrbent ends extend in opposite directions. These *ends terminate a sufficient distance from the end of the strap or Web to permit of inserting or removing the transverse orpliametrically extending end portion 23 of the coil spring 14.` To assemble the parts,the strap or web is turne-d at an angle to the transverse or diametrically extending end portion of the spring and moved toward the same andthen turned to bring the parts into engagement. After they are engaged andthe shock ab# soi-ber assembled upon. the motor vehicle,A

the strap or web will alivays be under tcnsion, an-d furthermore Will have no tendency to rotate relative to the spring `so that the parts Will remain in enga-gement. f

i In the modified construction shown in Figures 3 ande the shock absorber is adapted to be connectedlto the rear axleof *the motor vehicle instead of tothe front axle. The frame of this shock absorberA comprises the complementary sections 24 and v25 which are secured to each other by the bolts 26 and are adapted to be secured to the under side Vof the motor vehicle trame by. the'bolts I lach of thecomplementary sections has the.

internal 1,substantiallyl semi-circular channel 28 adapted to register with the channel of the other section :and together forming a main channel slidably engageable` in by the strap, or web 29, one end of Which is secured tothe rear axle housing 30 and the other end of Which is secured ,to the outer end of the `ol Spring 31-l This @eil Sprint-.fais housed between the horizontally rextending portions 32 of the Shock absorbertram@ which are proyided Withelongated recesses for receiving the Coil spline The @haheels 28 of `the shock absorber traine areso formed that the major yportion of the friction bear; ing surface is formed upon the lower `Wall and a 11i-inw Perdon. isformed `1.110011?the 11pira Wall adjacent tothe Sirneahellsine- The complementary sections 24 and 2 5 are also `formed to embrace and holdthe yield-' able bumper Which is positionedso that it is engageable With the upper lside of the axle housing 30; l .A

rom` the above description, Vit will be readily seen thatI have provided ,a simple construction of shock absorber` Whichgis very compact.` Also, this shock absorber being made of complementary sections maybe die cast,l thereby decreasing the cost othmanit facture `and at the same time permitting of greater ease n in assembling. Furthermore, the shock absorber carries a `bumper tor yieldably limitingthe(movement` of the aXle toward the trame of the motor vehicle.
